To control the operation of the motor I by remote control as hereincontemplated, means are provided for automatically adjusting andcontrolling the spark and gas mixture from the stop position to maximumspeed. In the motor as herein shown, a single lever 1 adjusts the sparkand synchronously through the use of a cam 8 simultaneously adjusts thepassage of gas from the carburetor 9 to the motor I.

'As in many outboard motors, the engine is provided with a magnetofly-wheel. The ignition' system or magneto and fly-wheel areconstructedas a unit, the fly-wheel l8 being mounted upon or formingpart of a cup-shaped housing I i which forms with the armature plate l2a com-- plete enclosure for the ignition system. The armature plate doesnot rotate with the fly-wheel l0 and housing 12, but is secured to thelever I and rotates therewith through the limited arc of movement of thelever in adjusting the spark. The complete ignition system, includingthe flywheel, is mounted within an external housing l3 having adepending peripheral flange M. The cup-shaped housing H and fly-wheel H)are keyed to and rotate a crank or drive shaft it which in turn rotatesthe propeller (not shown) for operating the boat.

Disposed at the front of the housing I3 is an elongated and arc-shapedmember 13 secured to the housing by a pair of end brackets l1, IT. Thismember throughout the greater portion of its length forms a downwardlyopening channel !8 with the rear flange 18 thereof at a pointintermediate its length providing a depending lug 23 for supporting andto which is attached a pulley housing or casing 2|. At each of itsopposite ends the member It provides an enclosure or housing 22 in eachof which is journalled a pulley wheel 23 upon a stub shaft or pin 24.Tubes or conduits 25 connect the opposite sides of the casing 2i to theadjacent sides of the enclosures or housing 22 and these tubes orconduits are adapted to receive cables for remote operation and controlof the motor. To permit ready removal of the member l8 and permitremoval of the motor I for storage or assembly on another boat, the endbrackets are secured thereto by winged nuts 25.

Disposed above the member i6 is the control lever I and an upstandinghandle 2'! for adjusting the spark and gas supply. Generally this handleand lever are moved or adjusted manually by the operator when seated atthe rear of the boat, but the present invention contemplates moving andcontrolling the movement of this handle and lever from the front of theboat. To accomplish this movement, an endless or continuous length ofsmall diameter cable 28 (preferably wire of approximately 1 inchdiameter) and having its ends connected by an adjustable turnbuckle 29is securely clamped or anchored at 39 between a clamping plate 3| andthe inturned end 32 of a bracket 33 having its upper end 34 secured tothe handle 21 by attaching screws or.

the like 35. The end or part 36 of the cable projecting to the right ofthe lever I and handle 21 (see Figs. 3 and 4) passes over the pulleywheel 23, then through the tube 25 and over a pulley wheel 31 rotatablymounted within the pulley housing or casing 2|. The cable 28 then passesthrough one of a pair of flexible tubes 38 and over one of a pair ofpulley wheels 39 journalled upon a stub shaft 40 in a housing or casing4! (see Figs. 2 and 6), mounted in the bottom of the boat at the sternend. Next the cable passes through one of a pair of tubes or conduits 42having one end disposed in the casing 4! and the other end in a housingor casing 43, the cable passing over one of a pair of pulley wheels 44rotatably mounted on a stub shaft 45 in the housing or casing 43 securedin a, corner and beneath a. knee at the rear of the boat. This cable 28then extends from the pulley 44 along one side of the boat to adjacentthe forward end thereof where it passes into a housing or pulley casing48 secured to a side of the boat adjacent the operators seat 41 andsteering wheel 5. In this casing the cable 28 passes over a large pulleywheel 48 and is anchored thereto at 49. This wheel is secured upon astub shaft 58 and pinned to the outer end of the shaft is a controlhandle 5|.

The section 52 of the length of endless cable 28 continues around thepulley wheel 48, over the small pulley wheel 53 and then rearwardlyalongone side of the boat and parallel to the other section of the cablewhere the ends are preferably connected by the turnbuckle 29. It thenpasses into the casing 43, over the other pulley wheel 44, otherparallel tube or 42 and into the housing or casing 4!. In this casing itpasses over the second pulley wheel 39, through the other or secondflexible tube 38 and over the second pulley wheel 31 in the housing orcasing 2|. It then passes through the other tube or conduit 25, pulleywheel 23 and anchored or clamped at 30 to the clamping plate 3! andbetween it and the inturned end 32 of the bracket 33.

Thus by rotating the control handle 5| and its stub shaft 50, the largepulley wheel 48 is rotated in a clockwise or counter-clockwise directionand the endless cable moves the singlelever l to the right or left tothereby advance the spark and increase the gasoline or fuel feed, or toretard the spark and decrease the feedin of the gasoline or fuel. Asstated above, the single lever as shown controls both the spark and fuelsupply and the latter is accomplished by providing the lever l with thecam 8 in the form of a depending bracket 54 secured to or formed on theunderside of the lever. The cam face 55 is adapted to engage or contactan upstanding projection or roller 56 disposed at the outer end of anarm 51 pivotally mounted upon the upstanding shaft 58 controlling thecarburetor 9. A stop 59 engages the cam face 68 on the arm 51 and limitsits throw or path of movement. The carburetor may be of any suitabledesign and may be provided with an adjustment at SI for controlling theflow of gasoline or fuel.

It will be appreciated that the means and manner of mounting theattachment including the housing 2|, the solid, endless cable passingover a plurality of pulleys and through the flexible tubing 38, permitsthe outboard motor to be rotated or turned through any angle or arcrequired for proper steering. This flexibility of mounting and themanner of connecting the conduit 5 ea t. a
